Researches on curves of the second order, also on cones and spherical conics treated analytically, in which the tangencies of Apollonius are investigated, and general geometrical constructions deduced from analysis; also several of the geometrical conclusions of M. Charles are analytically resolved, together with many properties entirely original.
